Available through Caelera , the M21428 video cable driver is the only dual-differential output cable driver available in the market today and the first to support 2.5V operation in addition to legacy 3.3V.

The differential outputs eliminate the need for two discrete external cable drivers, reducing system cost and simplifying design.

The M21428 is a high-speed, low-power, low-jitter cable driver designed to drive serial digital video data through 75-ohm coaxial cable typically used in SMPTE and DVB-ASI video applications.

The M21428 cable driver is optimised for performance from 143Mbps up to 2970Mbps with selectable slew rates for SD and HD/2xHD applications.

The typical output rise/fall time of the M21428 is 100ps for HD and 2xHD rates and 600ps for SD rates. The default output voltage swing is compliant with SMPTE 292M, 259M, 344M and 424M using a 750Ω 1% resistor.

The M21428 is pin-compatible with the M21418 and M21408 (except the M21408 has no SD/HD slew rate control). The M21428 supports a maximum single ended output swing of 1800 mVp-p when configured appropriately.
